U need a valve spring compressor. Mine's a `Meco'. Good ones are ~$50 or so. Cheapo ones are cheaper.
Try Repco, Supercrap, AutoPro, etc.

hye i have a998 head or 850 i think, how do you remove the valves, when there in the head with the springs still attached to them, currently stripping the head for it to go to the machine shop is there a special tool that alows me to remove them without the spring going through the roof of my garage ? if so does anyone know where i can get one or is someone selling ? cheers steve |

Doc...if you are sending a head to be machined (say) and you are not going to reseat the valves (lets just say they are fine).... how important is it to put the valves back in the same place 
Common sense would say put them back in the positions that they came from...but is it that critical

It's easy to get em back into the right spot anyways. Get a block of wood, drill 8 holes, number each hole from 1 to 8, put the first piston in the number 1 hole and so on. Easy as that! |

I would at least wire brush the crud off, and lap them back in with some coarse paste.. As said, a block of wood with 8 numbered holes in is fine. Or number the valve heads with a marker pen. If you are getting the valves and seats refaced, it really doesn't matter how they go back- but I always give them a quick lap with paste, just to ensure the machinist didn't f*** 'em up.

The supercrap ones are good enough for your needs - i bought one 10 years ago and is still not bent. But the Meco looks the good(and the price is right too...lol) Rob Forsyth Miniot!! |

Every time I have played with valves....I have always kept track of where they went...even back in 1965 on my first Mini where I used a cardboard box with holes in it for the valve numbers. OK ...didn't make myself clear....you have yourself a reasonable new multi angled valve seat set-up that has been done by an engine reconditioner say a year or two ago.... apart from carefully removing any carbon build up....I would have thought you use a very fine paste if anything so that you didn't stuff up all the nice machining work on the valves and seats.... |

Just google on valve seats and angle say..plenty of stuff to read.... |
